The nice thing is that so much really excellent bourbon can still be had for between $15 and $25 a bottle. There are some bourbons in that price range that are so nearly equal in flavor and aroma to bourbons costing $30 to $50 that comparison is almost pointless, and you'll find discussions about them all right here. Value for dollar wise, bourbon is really hard to beat, and between light and heavy, sweet and spicy, low proof and high proof, and so forth, there's pretty much something to please everyone.
And please them again, and again, and again . . .
